Review on 💧 Purenex ASOV Auto Valve 1 Pack: Your Solution for Speedy and Convenient Automatic Water Flow Control by Mark Harrison

I bought this valve to replace a 3 year old valve that still worked. I didn't want it to fail so I replaced it. This new valve did not work at all. It should shut off the flow when the tank pressure is about 2/3 or more of the inlet pressure. This valve did not close at all. BEWARE! He would have poured water down the drain forever. I put the old valve back in and it works perfectly. If you buy one of these you need to make sure it turns off. i will return it
